Chassis Mounting Sleeve

The Chassis Mounting Sleeve provides support and accurate positioning at various chassis connection points. We offer a wide range of material options to meet your specific strength, cost, and processing requirements. Our standard options include 10B21, SWRCH10A, 20Cr, and 20# steel grades. The 10B21 grade contains a small amount of boron, which provides good hardenability for through-hardening applications. The 20Cr grade is particularly suitable for components that require a carburized case layer for better wear resistance. We first cut the raw bar stock to length using a sawing machine or automatic cutting unit. We then drill the center hole and chamfer both ends. The chamfer angle on our product is made according to your drawing, which helps make installation easier for your assembly team.

We keep a wide range of standard material grades in stock. This allows us to start production of popular sizes within three working days after order confirmation. Our CNC lathes are programmed to maintain tight coaxiality between the inner and outer diameters. We guarantee coaxiality within 0.05 mm, which helps ensure proper alignment with mating components. For surface protection, we offer zinc-nickel plating and electrophoretic coating. The electrophoretic option provides a dark gray, matte finish that matches well with other chassis parts. Zinc-nickel plating provides strong corrosion resistance, especially in wet or salty environments. Our engineering team reviews your operating conditions and recommends the most suitable surface treatment for your Chassis Mounting Sleeve.

Our pre-sales engineering service includes material selection advice based on actual working temperatures and mechanical loads. We consider factors such as peak clamping force, thermal expansion, and exposure to road chemicals. We also support mixed-material orders, so you can combine different sleeve grades in one shipment without placing multiple purchase orders. Our customer service team records every inquiry and piece of feedback we receive. These records help us improve our manufacturing processes and reduce recurring issues. Our Chassis Mounting Sleeve has been successfully used in numerous subframe projects and is now exported to several countries as part of complete vehicle assemblies.
